AUTOMATIC nmznrca'ron.

Application filed November 16, 1925. Y Serial No. 69,405.

This invention relates to anv automatic(l lubricator device forautomobiles andthe like.

cluded the frame and the running gear andA such other parts as may becarried thereby and require lubrication and for which automaticlubrication isnot otherwise provided, such as for example, the engine.

The chief feature of the invention consists in the peculiar constructionof the lubricator, whereby the same is intermittent` ly operable andautomatically operable and whereby the same also may be manuallyoperable whenever desired, neither of the before mentioned .operationsinterfering whatsoever 'with the other. Y

The full-,nature of the invention will be understood from theaccompanying drawings and the following description and claims:

In the drawings Fig. 1 is a side elevational view of a portion of thevehicle chassis including the -frame and running gearwith which theinvention is associated and upon which it is mounted. Fig. 2 is alongitudinal Central sectional view through the lubricating device. Fig.3 is an end View of thel device'taken on line 3-3 of Fig. 2 and in thedirection of the arrows. Fig. 4 is a view similar to Fig. 2 and of apart vof the device and of a modified form thereof.

`Tn the drawings 1() indicates a frame of a chassis of a self propelledvehicle. dicates'the wheel supporting the same and having the axlemounting A12 carried by suitable spring means such as a leaf spring 13,suitably connected to the frame and carried thereby as by the shackle 14and other means as may be desired. Rigidly mounted upon the frame' 10 isa casing 15 from which projects a-hand wheel 16 and a shaft 17 uponwhich is mounted a lever 18. The lever 18 is positioned between theframe and axle and is adapted to be engaged by the axle in the reboundmovement thereof and move from the full line position to the dotted lineposition. This constitutes the power applied to the lubricator and therougher the rods the greater the lubrication required, and therefore thegreater the amount of lubricant supplied to the chassis 55 bearings.

Carried by the housings l5 is a lubricant reservoir 19 in the form of 'acylinder. Slidably mounted within said reservoir is a piston 2O having acentral threaded opcning 21 in which is rotatably mounted a scrcwthreaded member yorshaft 22. The piston is apertured las at 23 andslidably supported therein is a rod .or guide 24 which 'extendslongitudinally of the cylinder and prevents rotation of the piston withthe screw threaded shaft 22. Thus rotation of shaft 22 will cause thepiston 20 to advance or retire in the cylinder 19. r lVhen said pistonadvances it forces the lubricant ahead of it out through theseveralconduits 25 and 26, which conduits 25 and 26 each are associatedwith aport 27 and 28, respectively. The ports 27 and 28 communicate with acommon supply duct- 29 in open communication with the cylinder 19 saidports and ducts being carried by block or cylinder head 30; Mounted ineach one of the ducts 27 and 28 is a plunger 31 and 32, respectively.TheV peripheral series ers 31 are reciprocated to .and fro in therotation of the cam 33 secured to and rotatable with the shaft 22. Theplunger or pistons 31 are reciprocated to and fro in the same manner bythe -cam 34 similarly secured to the shaft 22. Thus as the shaft 22 isrotated the pistons 31 and 32 are reciprocated to and fro and forcelubricant under pressure to the respective conduits 25 and 26 for thelubricant is supplied to ports 27 and 28 by ducts 29, which in turn arein 'communication with the cylinder through the medium of the ports 35in the cam 33, and said lubricant is supplied therethrough underpressure by reason of the advance of the piston. It will be readilyapparent, therefore, that rotation of shaft 22 by handle 16 whichA issecured thereto without the housing, causes the shaft to rotate andforces lubricant under pressure into the supply ducts 29 andout throughthe several connections 25 and 26 by means of the reciprocations of therespective plungers.

The means for securing the automatic rotation of shaft 22 comprises a'pawl 40 pivotally mounted on the shaft 17 and eccentrically mountedthereby. Pawl 40 engages the ratchet 41 concentric with shaft 22 fplungcylinder head having intake ports communi-l but loosely mountedthereon. Ratchet 4l is a continuation of the gear formed hub 42 meshingwith the idler gear 43. Idler gear j 43 is a continuation of pinion 44which simibounding o the Wheels with respect to the frame automaticallycauses the ratchet 41 to rotate in the desired direction and through thegear reduction provided rotates shaft 22 to advance the piston andreciprocate the plungers.

The plug 46 is provided for filling the cylindervvhen necessary.

In Fig. 4 a modified form of the invention is illustrated and in this.form there is provided but a single annular series of supply ducts 126having the supply ports 128, said ports being in communication withsupply ducts 129 carriediby the head 130. Plungers 32 andcam 34 areoperable by shaft 22 the same as shown in Fig. 2.

The invention claimed is:

1. In a multi-stage pressure lubricator device, the combination of arotatable shaft` Ia cylinder enclosing the same and including a port andeach similarly reciprocable rela' tively to said shaft, and cam meanscarried by said shaft and rotating therewith for reciprocating saidplungers.

2. A device as defined by claim 1 charac` terized by the ports beingarranged in annular series and in a plurality of series, and a commonsupplyl duct adjacent the ports in concentric-Series.

3. A device as defined by claim 1 characterized by the ports beingarranged in annular series and in a plurality of series, and a commonsupply duct adjacent the ports in concentric series, the concentricports and ducts being radially arranged.

4. A device as defined by claim 1 characterized by the ports beingarranged in annular series, and a pairof cams carried by said shaft,said ports being arranged in a pair of annular series, said coaxial camseach being A associated with the plunger of each of said annular series.

In Witness whereof, I have hereunto af-
